Key Seismic Design Considerations at the Start of Project (Schematic Design)
Fong & Chan Architects (FCA) Webcor Builders
• SFGH is located approximately 10 km
(6.2 miles) from the San Andreas Fault.
• Site will likely experience high peak
ground accelerations during a major
earthquake event. This level of shaking
is quite significant and can result in
major structural and non-structural
damage.
• SFGH is one of the most critical health
care institutions in the San Francisco Bay
Area and operates the only Trauma
Center servicing San Francisco and
Northern San Mateo County.
